Answer:
30°
Step-by-step explanation:
Line AB and BC are tangents to the given circle.
Alternatively, <ABC and <AOC are supplementary because AB and BC are tangents.
The correct choice is A.
Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
The answer for 16 is A and for 17 is A
Answer:
117° since they are alternate exterior angles
